What training should come with your first Trimix prescription?

Your first Trimix prescription should come with more than a vial. Before the first dose, you should know exactly what's in it, how much to draw up on the syringe you were given, how to store it, how to dispose of used needles, how to report your response, and what to do if an erection won't go down. If any of that is unclear, don't inject until it's answered.

What MintRx helps you get clear on

Injection treatment works best when the medication side is clear before you start. A MintRx pharmacist can walk through your label, your concentration, your syringe, your storage and your plan, and you can come back with questions after any dose that didn't go the way you expected.

A review of your health and medicines

Before prescribing, the licensed provider should review your erectile symptoms, health history, previous treatments, and current medicines. Include nonprescription products and supplements, not just medications listed in a patient portal.

Tell the provider about blood thinners, previous prolonged erections, penile curvature, scarring or Peyronie's disease, a penile implant, and blood conditions such as sickle cell disease. These can raise the risk of priapism or bleeding, or rule injections out. Don't stop a blood thinner on your own to make injections possible. A prescription is a clinical decision, not an automatic result of a questionnaire.

What should come in the box, and on the label?

MintRx's Tri-Mix prescription comes with the prescribed vial, syringes, alcohol swabs and written instructions. Before your first dose, check:

• The label: the three ingredients (papaverine, phentolamine and alprostadil) and the concentration of each. Trimix comes in different strengths, so the name alone doesn't identify your prescription.
• Your prescribed amount, matched to the syringe that came with it. The same marking can hold a different amount of medicine in a different formula, so ask your pharmacist to show you exactly where your amount sits.
• How often you may inject, as written in your directions.
• Storage: keep it refrigerated at 36 to 46°F (2 to 8°C), write down the date you first puncture the vial, use an opened vial within 28 days, and never use it past the beyond-use date on the label.
• Disposal: where used syringes will go before you need to throw one away.

If the label and your written instructions don't match, stop and ask before using it. The guide on what to ask before requesting a Trimix prescription goes deeper on concentration, syringe markings and vial size.

A larger vial does not, by itself, mean a stronger medication. Likewise, a familiar product name does not establish that a refill has the same concentration. Check the label and ask about any change before using it.

Written boundaries for treatment

Your written plan should state the prescribed amount, permitted frequency, and instructions for an inadequate response. It should also explain who can authorize a change.

Do not take an extra injection because the first result seems disappointing. Do not increase the amount on your own or combine Trimix with another erectile dysfunction treatment unless your prescribing clinician has specifically directed that combination.

After each dose, jot down the amount, how firm the erection was, how long it lasted and any pain. That record is what your provider and pharmacist need to decide the next step.

What's the plan if an erection won't go down?

Set this up before your first dose, not in the middle of a long night.

• At 3 hours: start making plans. Call your prescriber or the MintRx team so they know what's happening, decide which emergency department you'd go to, and line up a ride.
• At 4 hours: go to the emergency department, even if it doesn't hurt. Don't wait for a callback, a portal reply or the next business day.
• Severe pain or anything else that worries you: get seen sooner. Four hours is the outer limit, not a reason to sit through worsening symptoms.

An erection lasting more than 4 hours is a medical emergency because it can damage erectile tissue. Bring the vial or a photo of the label, and tell the team what you injected, how much and when.

Have pseudoephedrine on hand before your first dose. Pseudoephedrine (original Sudafed, sold behind the pharmacy counter, not Sudafed PE) is an over-the-counter option you can try if an erection hasn't gone down after an hour or two. Ask your prescriber or MintRx pharmacist ahead of time whether it's safe for you, because it isn't right for everyone, including people with uncontrolled high blood pressure or heart disease, or anyone taking an MAOI. Follow the package directions.

Pseudoephedrine is a first step to try, not a substitute for emergency care. If the erection lasts 4 hours, go to the emergency department even if it doesn't hurt. After any unusually long erection, your treatment plan needs review before your next injection.

Why this matters

Injection treatment can help some adults with erectile dysfunction, including people whose previous treatment has not worked well enough. It also requires preparation that a pill does not: handling a needle, measuring a prescribed amount, and responding appropriately to a prolonged erection.

The goal of training is not simply to make you comfortable with the equipment. It is to make sure you can follow the prescription and recognize when to stop and seek help. Confidence without clear instructions is not enough.

Your checklist before the first home injection

Use this before your first home injection. Each topic needs an answer specific enough that you can follow it at home without guessing.

Keep the written instructions somewhere you can find them easily. If the pharmacy label and the clinician's instructions appear different, resolve the difference before using the medication.

Before your first home injection

1. Provider review. A licensed provider decides whether injection treatment fits your health history and goals.
2. Medication check. You confirm the formula, concentration, prescribed amount and syringe with the pharmacist.
3. Written plan. Your directions, injection limits and emergency plan are in one place.
4. A way to report back. You know how to tell your provider and pharmacist what happened after each dose.

If you feel faint around needles, have difficulty reading syringe markings, or have limited hand movement, say so before you start. Those are practical care needs, not reasons to feel embarrassed. Your provider needs that information to assess whether you can use the treatment safely.

Which risks should you understand before starting?

Training should cover both the potential benefit, an erection suitable for sex, and its limits. Trimix does not guarantee a response, and it is not appropriate for everyone.

Meaningful risks include injection-site pain, bruising or bleeding, infection, scarring, and a prolonged erection. Some complications need urgent evaluation rather than a routine message to the care team. Ask which symptoms mean you should stop using the medication until you have been assessed.

Discuss what to do if you notice a new lump, increasing curvature, persistent pain, or a concerning change at the injection site. Do not solve a new problem by moving the injection elsewhere and continuing without advice.

Trimix is compounded. The FDA explains that compounded drugs are not FDA-approved and do not undergo the agency's premarket review for safety, effectiveness, and quality. Evidence or instructions for one ingredient or formulation should not be treated as proof that every compounded preparation is equivalent.

Who handles questions after a prescription?

The roles should be distinct, even when several people contribute to your care.

• Licensed provider: evaluates suitability, makes prescribing decisions, and decides whether treatment should change.
• Pharmacy team: answers medication questions, including label interpretation, storage, supplies, and concerns about the dispensed preparation.
• Client Care: handles account and order questions and routes requests to the appropriate team.

Your MintRx pharmacist can help with the medication itself: reading the label, finding your amount on the syringe, storage, and making sense of how a dose worked. Treatment changes stay with the prescribing provider, and emergencies go to emergency care. The guide on when to call the pharmacy team explains which questions go where.

What should you confirm before a refill?

A refill is a useful checkpoint, especially if the label, syringe, or written directions look different. Compare the formulation and concentration with your current prescription, then ask the pharmacy to explain any difference.

Also report a response that has changed, new side effects, or difficulty following the injection routine. Keep a simple record of what happened and share it with the prescribing clinician. Do not use that record to adjust treatment yourself.

Follow-up matters past the first box. In a large sexual medicine clinic program of more than 1,400 men, most using Trimix, injections worked for most of them, yet many had stopped within three years, some because their own erections or pills started working again. Treat your first prescription as the start of a conversation. When you're ready to reorder, see how to request a refill in the patient portal.

FAQ

Know the plan before the first dose

The most useful question isn't just whether you understand the injection. It's whether you know what you'll do when something doesn't go as expected.

Before your first home dose, keep your label, written instructions and emergency plan together. If anything is unclear, talk with a MintRx pharmacist before you inject. Comparing other options first? See MintRx's sexual health treatments.
